Business: Tales of the 14th Floor

Across between a fortress and a cathedral, the General Motors world
headquarters in Detroit is as impregnable as the corporation it houses.
The company cultivates an image of efficiency and dignity, taking
special care to preserve an aura of sacrosanct wisdom in its most
senior executive offices on the 14th floor of the building. But an
entertaining and surely controversial new book makes that aura look
more like a fog as it lifts some of the confidentiality from the
world's largest industrial corporation.
